IMPROVEMENT THE4 CONSTRUCTION OF CHIMNEYS AND FLUES.

The" Schedule referred to in these Letters Patent and-,making partof Iche same.

To` all whom 'it may concern Be it known tha-6I, JOSEPH Krlnoiixnn, of Mott? ville, in the county of St. Joseph, and State'ot Michigan, have invented certain new and useful Improvements` in Molding and Constructing Flnes t'or Buildings` and other purposes; and I do iereby declare' that the following is a full, clear, and exact description of the same, reference heilig had,fto t-he accompanying' drawings thereof" which make `part ot' this speciication, and in whichi Figure 1 represents a. ve.`rtieals`cction, showing a ue formed between the joists of the fiom-ing` ofa building, and a collapsible sand-bag core to form the tlne. y i

Figure 2 represents a horizontal section through tlie'same.` j i j Figure 3 represents a verticall section of' the,same, showing thecollapsiblc core removed,laml a section i of pipe inserted within the i'lue.`

I My invention `relates tomolding and constructing fines` for buildings and other purposes,'and consists in tbrming'a flue in a square .compartment between lthe joists of a building, and In'oviding the interior thereof with foundation supports and a number ot' nails project-ing into the compartment, in such manner as to imbed themselves intothe cement, and thus constitute askeleton 'amefforthe latter, of which the tine is formed.

i Also, in molding the flue of cement, by means of `a collapsible sand-bag core, so that it may be readily `withdrawn therefrom when the cement has In the accompanying drawingsl A represents two ot' the joists otl the floor in scctfiion, and v B, cross-boards secured between them, so as to form V a square compartment,.(), within which the tine Dis formed. p I

Nearthe'bottoin of this compartment, yl secure supports or cleats E, projecting suiiieiently t'ar therein to serre as a foundation for the cement 1?, and within the interior of this compartment tln'onghout its sur.- faee, asnitable @number of tour-penny nails, a, is driven, extending into said compartment about halt their length, so as to form a skeleton frame for the body l of the cement, and thus support and lock it securely `to the sides ot' the compartment (I, the shank a ot each nail forming a vertical support, while the heads b thereof brace it horizontally, so that the cement F will bear a very grea-t pressure without being displaced. i

'lhe bottom 0i' the liuc is then temporarily closed by a board, G. n

l -OM- XVithin thecenter ot' the compartment C thusconstructed, I suspend, by any convenient means, a sack1 l-I, ot' yperfectly dry sand, so as to just rest upon the bottom board G. Thediameter of the sack must be equal throughout its length, and a little greater than the diameter of the pipe which 'is to pass through the tine l). lhe collapsible core ll thus formed and centered, is held in position by its weight, so` that it cannot move out ot' center as the cement is introduced. The cement is then pom'ed into the chamber around the sack until theformer is filled.` As soon as the ,cement has set, the bottom board Gis removed, the sac-k H is cnt at its lower end, and the sand emptied therefrom into another sack or other convenient receptacle. The sack is then removed by drawing or peeling it from the cement, and the flue is completed, leaving the sack in a condition to be again used.

The sack is made of any suitable material, and,` with the sand,`is used to form the core ofthe cement,

because any other material would adhere thereto, so that it could not be withdrawn, and, from the equal n'essure ofthe. cement around it alwars maintains a y a e A ilue thus molded and constructed, can be used where any tlne or thimble is required, vertically or horizontally through partitions, doors, or walls, and when formed ot my improved roulent is a safeguard against accident by tire.

When theflue is formed between the joists of' tlooring, it may be plastcredaronnd the bottom of the foundation supports, and protected at its top'bya' piece ot'zinc,tin, or carpet, f

As the cement used in the construction of, these Y lines forms the subject of another application `for a patent, of even date herewith, it need not bc particularly described.

Having described my invention.

I claim- 1. A ue compartment, constructed with foundation supports E, and .holding and bracing-nails a b, substantially as herein described.

2. A cement tine, D, supported and locked securely in posit-ion by means of an ope-n skeleton frame, substantiallyas herein described.

3. In molding cement iucs, the use of a collapsible core, made ot' canvas or other suitable material, and

,filled with dry sand, or its equivalent.' JOSEPH KLEGKNER.
